Devices for blood capture and reintroduction having a filter

Abstract

A blood reintroduction system may include a canister configured to collect blood. The system may include an inlet configured to be fluidly connected to a first tubing in fluid communication with an aspiration system configured to apply aspiration to a vasculature of a patient. The system may include a first outlet configured to be fluidly connected to a second tubing in fluid communication with an aspiration pump. The system may include a second outlet configured to interact with a blood reintroduction device, wherein the blood reintroduction device is configured to withdraw the blood collected inside the canister. The system may include a filter positioned inside a flow path leading to the second outlet.

What is claimed is: 
     
         1 . A blood reintroduction system, comprising:
 a canister configured to collect blood;   an inlet configured to be fluidly connected to a first tubing in fluid communication with an aspiration system configured to apply aspiration to a vasculature of a patient; the inlet configured to direct an incoming stream of blood circumferentially along an inside surface of the canister;   a first outlet configured to be fluidly connected to a second tubing in fluid communication with an aspiration pump;   a second outlet configured to interact with a blood reintroduction device, wherein the blood reintroduction device is configured to withdraw the blood collected inside the canister; and   a filter positioned inside a flow path extending through the second outlet.   
     
     
         2 . The blood reintroduction system of  claim 1 , wherein the filter is positioned between a chamber defined by the canister and an opening of the second outlet; the filter configured to filter the blood before the blood are withdrawn from the canister via the second outlet. 
     
     
         3 . The blood reintroduction system of  claim 1 , wherein the inlet is positioned on an upper portion of the canister 
     
     
         4 . The blood reintroduction system of  claim 1 , wherein the first outlet is positioned on an upper portion of the canister. 
     
     
         5 . The blood reintroduction system of  claim 1 , wherein the canister further comprises a base defining a blood collection cavity. 
     
     
         6 . The blood reintroduction system of  claim 5 , wherein the filter is at least partially disposed inside the cavity, and wherein the second outlet is positioned adjacent to the cavity. 
     
     
         7 . The blood reintroduction system of  claim 1 , wherein the blood reintroduction device comprises a syringe. 
     
     
         8 . The blood reintroduction system of  claim 1 , wherein the blood reintroduction device comprises a venous line in fluid communication with vasculature of the patient, and wherein a pump fluidly connected to the venous line is configured to advance the blood withdrawn from the canister into the vasculature of the patient. 
     
     
         9 . The blood reintroduction system of  claim 1 , wherein the aspiration system comprises a thrombectomy catheter and an aspiration catheter configured to be advanced through the thrombectomy catheter. 
     
     
         10 . The blood reintroduction system of  claim 1 , wherein aspiration from the aspiration pump is configured to draw blood from the first tubing into the canister. 
     
     
         11 . The blood reintroduction system of  claim 1 , wherein a longitudinal axis of the second outlet is positioned at an acute angle relative to a base of the canister. 
     
     
         12 . The blood reintroduction system of  claim 1 , wherein a longitudinal axis of the second outlet is positioned at a right angle relative to a base of the canister. 
     
     
         13 . The blood reintroduction system of  claim 1 , wherein the first and second tubing are configured to permit the canister to reside within a sterile field. 
     
     
         14 . A canister for use in a blood reintroduction system, the canister comprising:
 a housing;   a base comprising a floor, the floor defining an inclined surface and a blood collection low point; the housing and the base defining a chamber configured to collect blood;   an inlet configured to be fluidly connected to a first tubing in fluid communication with a thrombectomy catheter, the inlet oriented to direct flow of blood along an interior side wall of the housing;   a first outlet configured to be fluidly connected to a second tubing in fluid communication with an aspiration pump;   a second outlet configured to interact with a blood reintroduction device, the blood reintroduction device configured to withdraw the blood collected inside the chamber; and   a filter disposed between an opening of the second outlet and the chamber.   
     
     
         15 . The canister of  claim 14 , wherein the inlet and the first outlet are positioned on an upper portion of the housing. 
     
     
         16 . The canister of  claim 14 , wherein the inlet and the first outlet are positioned in an elevated position relative to the second outlet. 
     
     
         17 . The canister of  claim 14 , wherein the filter comprises a proximal end and a distal end; the distal end of the filter positioned adjacent the blood collection low point. 
     
     
         18 . The canister of  claim 14 , wherein the filter and a bottom surface of the base define an acute angle. 
     
     
         19 . A filter assembly for use in a blood reintroduction system, the filter assembly comprising:
 a filter housing comprising a proximal end and a distal end:   a cap removably secured to the proximal end of the filter housing   a filter comprising a proximal end and a distal end, the filter positioned inside the filter housing; and   a luer fitting secured to the cap, the luer fitting configured to be in fluid communication with a blood reintroduction device;   wherein the filter housing is configured to be at least partially disposed inside a canister.   
     
     
         20 . The filter assembly of  claim 19 , wherein a longitudinal axis of the filter housing is positioned at an acute angle relative to a base of the canister.
